摘要： Method for isolating carboxylic acid from an aqueous alkali metal carboxylate-containing side stream, e.g., the aqueous side stream of an organic peroxide production process, with co-production of alkali metal salt, involving adding an acid, or an anhydride, ketene or acid salt, to the aqueous side stream, thereby 5 forming carboxylic acid and alkali metal salt within the aqueous side stream, and separation of the carboxylic acid from the aqueous side stream.

摘要： Process for producing a salt comprising NaCl and/or KCl from the aqueous effluents from one or more organic peroxide production processes, said process comprising the following steps (a) ensuring the pH of the aqueous effluents to be in the range 1-5, (b) separating the effluents in a liquid organic layer and an aqueous layer, (c) removing the organic layer, (d) raising the pH of the aqueous layer to a value in the range 6-14, and (e) crystallizing the salt from the aqueous layer having a pH in the range 6-14.
